My prediction is Zelenasky will call for an ellection allowing Trump to fund the war without looking weak after the shut he said about Zelenasky.
It is a real possibility since iran and russia are working together and trump backs israel against iran. The logical next step is to back ukraine againts russia.
I wouldnt be too sure of that. Trump is a businessman who will take what he can and give back as little as possible. Trump got the presidency why honour any agreement with putin?
